Why each option

The `dig` tool is specifically designed for querying DNS name servers and provides detailed information about both the query sent and the response received.

Adnsq

`dnsq` is not a standard or widely recognized DNS debugging tool that provides comprehensive query details.

BdigCorrect

The `dig` (domain information groper) command-line tool is widely used for DNS lookups because it offers extensive debugging output, displaying the full query, the answer section, authority section, and additional records, making it ideal for troubleshooting DNS issues.

Chostname

`hostname` is used to display or set the system's hostname, not for DNS query debugging or providing query details.

Ddnslookup

`dnslookup` is not a standard command; while `nslookup` exists, it typically provides less detailed output compared to `dig`.

Ezoneinfo

`zoneinfo` often refers to time zone data or is not a standard DNS debugging tool.
